• An automated tuning utility that optimizes overclocking and cooling profiles for your unique system configuration.• Fans stay whisper-quiet with everyday computing, and deliver optimal airflow when the system is crunching through CPU or GPU-intensive tasks.• Stress test function helps optimize and overclock for CPU- or memory-centric workloads.

Fan Xpert 4: Flexible Cooling Controls for Air or LiquidWith WS X299 Sage, you have comprehensive control over fans, water pumps and even all-in-one (AIO) coolers — all via Fan Xpert 4 or our media-acclaimed UEFI. Whether you're cooling with air or water, Auto-Tuning mode intelligently configures all parameters with a single click. There's also Extreme Quiet mode, which reduces all fan speeds to below the default minimum — keeping your system whisper-quiet when performing light tasks.

Digi+ Power Control: Precise Digital Power ControlDigi+ delivers real-time control over voltage droop, switching frequency and power-efficiency settings, allowing you to fine-tune CPU voltage regulation for ultimate stability and performance.

Media-Acclaimed UEFI BIOSThe smoothest, slickest mouse-controllable graphical BIOS has been improved to make it even more appealing. Whether you're a PC novice or a seasoned overclocker, EZ and Advanced modes will help you find your way with ease.

EZ Tuning WizardQuickly apply a CPU overclock to improve system performance, or configure a RAID array for faster data retrieval and backups.

• Multiple Temperature Sources: Each header can be set to monitor and react to three user-configurable thermal sensors, for workload based cooling. It's all easily managed by Fan Xpert 4 or UEFI.• Water Pump+: A dedicated header that can supply over 3A to high-performance PWM or DC water pumps.• AIO Pump: A dedicated PWM/DC header for self-contained water-cooling setups.• 4-pin PWM/DC Fan: Every on-board header supports auto-detection of PWM or DC fans.• ASUS Fan Extension Card Support: Includes a header for fan extension card support.• Smart Protection: A dedicated integrated circuit protects each fan header from over-temperature and over-current.

Ultra-Efficient VRM HeatsinkDesigned for the powerful Intel Core X-series processor with up to 18 cores, WS X299 Sage features a capable thermal design to ensure maximum performance with no CPU throttling. Consisting of an ultra-efficient VRM heatsink with a metal fin array design that maximizes surface area for heat dissipation, plus an additional heatsink and connecting heatpipe to further increase cooling performance, this innovative thermal design ensures WS X299 Sage is always ready to handle any task, no matter how demanding.

Multiple PLX HeatsinksWith its dual PLX chips that increase the number of available PCIe lanes to enable 4-way GPU configurations, WS X299 Sage also features a robust thermal solution to dissipate the heat that comes with routing so much high-speed traffic. An additional heatsink array and heatpipe cover the PLX chips and are positioned in the path of maximum airflow within the chassis, reducing PLX temperatures by up to 20° C to ensure optimal cooling and system stability.

ProCool Power ConnectorASUS ProCool is the power connector reinvented. Compared with traditional power connectors, ProCool connectors provide a more secure, low resistance connection, enabling better heat dissipation and improved reliability.

VROC: Upgrade Your RAIDIntel Virtual RAID on CPU (VROC) obliterates PCH-based RAID arrays that are bottlenecked by the 32Gbps limit of the DMI bus, allowing you to utilize CPU PCIe lanes to configure a bootable RAID array that can transfer data at insane speeds.*A VROC key is required to enable VROC RAID arrays, not included.

Dual U.2 Connectors: Join The NVMe RevolutionThe revolutionary specification that lets your SSDs scream at top speed. Simply attach your choice of drive and experience data-transfer speeds of up to 32Gbps — and free up a PCIe slot for another expansion card.

Dual Intel® Server-Class Gigabit LAN: More Throughput, Less CPU UsageFor more reliable networking, WS X299 Sage features the latest server-class dual Intel® Gigabit LAN ensuring lower CPU utilization and temperatures outstanding performance as well as better support for diverse operating systems. The dual Ethernet ports also support teaming which combines the network links to provide higher throughput or redundancy in case of failure.

• Lower CPU workload.• High TCP & UDP throughput.

Reliable Stability and Validation

Server-Grade Memory ValidationWS X299 Sage supports up to 128GB of quad-channel DDR4 RAM to readily handle the larger data sets found in professional workloads. Strict validation with a wide variety of memory types and operating conditions — including factors such as time, temperature and voltage ranges — ensures that WS X299 Sage provides the reliability and stability professionals depend upon to get their work done.

SafeSlot: Protect your Graphics Card InvestmentSafeSlot is the PCIe slot reinvented by ASUS and engineered to provide protect your graphics card investment. Manufactured in a single step using a new insert-moulding process, SafeSlot integrates the slot with fortifying metal for an inherently stronger slot, which is then firmly anchored to the PCB through additional solder points.

These are exciting times to be in the market for a new CPU. AMD is back in the game with its competitive Ryzen processors, while Intel has upped the ante in the enthusiast space with a refresh of its High-end Desktop (HEDT).
